Abstract

Sistem hidroponik dapat menjadi salah satu solusi bagi pengembangan tanaman buah dan sayur dengan berbagai kelebihan dibandingkan sistem pertanian konvensional. Optimisasi linier merupakan teknik atau metode untuk mencapai hasil optimal dalam matematika yang persyaratannya opimalisasi fungsi tujuan dan kendala adalah linier. Untuk mengetahui berapa suplai nutrisi A dan nutrisi B supaya lebih optimal, bisa dilakukan mengoptimasi harga nutrisi. Karena dari harga kedua nutrisi bisa mengetahui berapa gram yang akan dilarutkan ke dalam air untuk pembuatan larutan nutrisi A dan larutan nutrisi B. Setelah dilakukan perhitungan optimisasi linier, didapatkan suplai nutrisi AB mix yang akan masuk ke hidroponik sebesar 53,2 L/panen. Untuk pencampuran nutrisi, larutan nutrisi A dan B terdapat suplai larutan nutrisi A sebesar 277,2 ml/panen dan suplai nutrisi B sebesar 255 ml/panen. Untuk kuantitas, pertumbuhan tanaman dengan monitoring pH lebih bagus daripada pertumbuhan tanaman tanpa monitoring pH. Sedangakan untuk kualitas, pengamatan dengan monitoring pH, tanamannya terlihat lebih segar dan pertumbuhannya lebih cepat daripada pengamatan tanpa kendali pH. Pengamatan tanaman Pakcoy tanpa monitoring pH, tanaman bisa mengalami pertumbuhan tetapi beberapa warna daunya terlihat warna kekuningan dan juga beberapa mengalami kerontokan ================================================================================================================== The hydroponic system can be a solution for the development of fruit and vegetable crops with various advantages over conventional agricultural systems. Linear optimization is a technique or method to achieve optimal results in mathematics where the objective function optimization requirements and constraints are linear. To find out how much nutrient A and nutrient B supply so that it is more optimal, you can optimize the price of nutrients. Because from the price of the two nutrients, you can find out how many grams will be dissolved in water for the manufacture of nutrient solution A and nutrient solution B. After the linear optimization calculations are carried out, the AB mix nutrient supply that will enter hydroponics is 53.2 L / harvest. For mixing the nutrients, of nutrient solution A and B there is a supply of nutrient solution A of 277.2 ml / harvest and nutrient supply of B of 255 ml / harvest. For quantity, plant growth with pH monitoring is better than plant growth without pH monitoring. As for quality, observations with pH monitoring, the plants looked fresher and grew faster than observations without pH control. Observation of Pakcoy plants without monitoring the pH, the plants can experience growth but some of the leaves look yellowish and some are shedding.
